ABSTRACT
This chapter describes a newly developed approach to CNC-controlled multi-axis systems geometric errors compensation based on optimal error correction strategy. It discusses a system for compensation of geometric errors of multi-axis equipment based on the new approach. The chapter also describes a new approach to multi-axis equipment geometric errors correction. It explores a multi-axis equipment geometric errors model is developed. The chapter provides the components of geometric errors are measured by multi-function Laser Measuring Information System (LMIS). It explains the geometric errors measurement approach based on measuring elementary components of error by means of LMIS and following calculation of total error. A system is built for automatic error distribution measurement, being an integrated complex, including, for example, multi-function LMIS Renishaw XL-80 and a machine-tool CNC system. The principles of system's implementation, results of measurements and system's functioning simulation.
